 # TODO
- - [ ] make a custon date parser for possibly up to 18 different versions(that 
-       is, for each possible tool).
- - [ ] Fix warning especially usage and restriction warnings once I'm
-       able to successfully parse all sample VCDs.
- - [ ] Change error messages to line and filenames. Go through all calls to ``format!``
-       whilst also keep performance in mind.
- - [ ] Create compressed fungible numeric enums with good heuristic support.
+
+## Features
+ - [ ] handle signals with x or z as string
+       - the one bit parsers may also need to handle string
+ - move parse_orphaned_vars to scopes.rs
  - [ ] Print out git commit or release number.
  - [ ] Should be able to load waveform whilst viewing it live.
        - could be quite challenging to implement for various reasons
+ - [ ] Take a look at GTKWave parser to compare efficiency.
+ - [ ] re-order all signal timelines as binary balanced trees with respect to timestamps
+       - support multithreaded re-ordering
 
+## Repairs
+ - [ ] make a custom date parser for possibly up to 18 different versions(that is, for each possible tool).
  - [ ] Consolidate error messages and add cursors throughout.
- - [ ] Consider what to do with don't care values
-       will probably just convert them to strings for now.
- - [ ] Include line and possible column numbers
- - [ ] Take a look at GTKWave parser to compare effificiency.
+ - [ ] Fix warnings especially usage and restriction warnings once I'm
+       able to successfully parse all sample VCDs.
+
+## Code Consistency
+ - [ ] Change error messages to line and filenames. Go through all calls to ``format!`` whilst also keeping performance in mind.
+
+## Marketing
  - [ ] Send survey to community channel.

-# Questions to Answer
- - [ ] Is it safe to assume that we may treat any values before the first
-       non-zero timestamp as having occured on `#0`?
-
-# Probably No Longer Needed
- - [ ] Should insert nodes in BFS order
